Mercury 200XL Verado - Driveshaft Seals Replacement

After removing the lower unit from your Mercury outboard, you should replace the oil seals and the impeller in one go.

While replacing certain parts might be easy, removing the lower unit to get to where they are is the hard part. With the lower unit removed, take advantage of the opportunity to replace all the seals at once, so you won’t have to drop the gearcase from your outboard as often.

Follow the steps below and watch the video above to learn how to replace an outboard’s driveshaft seals.

Tools and Parts Needed – Mercury 200 Input Shaft Seal Replacement

Tools

Screwdriver

Hammer

Parts

Lower unit seal kit

2-4-C grease

NOTE: The driveshaft seals and O-rings are not sold separately, so you’ll have to buy the complete lower unit seal kit, which includes all the seals, gaskets and O-rings for the shift shaft, as well as the prop shaft.

Before you can replace the shift shaft seals, you must remove the lower unit and the water pump from your outboard. Watch the videos below to see how to get both done.

How to Replace Mercury 200XL Verado Driveshaft Seals

Step 1. Press down on the driveshaft oil seal carrier to remove the tension on the retaining ring that holds it in place. Use a metal collar if you have one the correct size, or carefully tap down on the carrier with a hammer and screwdriver.

Step 2. Pry out the retaining ring and lift the oil seal carrier up and off the driveshaft.
